The 56-year-old singer said that finding love might be one of the reasons he now feels content.

"I am very happy. It comes from getting older, realising a lot of stuff and having kids growing up around you. I am enjoying myself, especially in the last few years," he said.

"It might be a few factors; finding the right person to fall in love with, having a greater sense of knowing myself and seeing all my good points and bad points and that sort of stuff. Generally I'm just more comfortable in my own skin.

Paul, who married second wife Hannah Andrews, the mother of his young twins, in 2010 , said he was halfway done on his new album, adding: "It's early days but what I've got so far is great."

The singer, who is performing at numerous festivals during the summer, added: "I'm always into what I'm doing at the time. I don't get too nostalgic about anything, there's not much point, and it can be heartbreaking too sometimes, so why would you? I just enjoy what I've got right now.
